UAR-CLOSING MACHINE.

Application filed February The invention relates to new and useful improvements in jar closing machines, and more particularly to a jar closing machine wherein the flange of the cap or sealing band is turned underneath the ledge on the neck of the jar for securing the closure to the ar.

An object of the invention is to provide a machine of the above type wherein spinning rolls are utilized for turning the lower edge of the flange of the cap or band underneath the ledge on the jar, and wherein said spinning rolls are so arranged and actuated that the jars may be fed to the spinning rolls one after another at random.

A further object of the invention is to provide a machine of the above type where in the jar passes between the spinning rolls after the flange has been properly turned underneath the ledge on the neck of the ar.

A still further object of the invention is to provide a machine of the above type wherein the spinning rolls are made with upper and lower sections, one of which engages the shoulder of the cap or band for forcing it down on to the neck of the jar, and the other of which engages the lower edge of the cap or band and operates to turn or tuck the same underneath the shoulder on the neck of the jar.

A still further object of the invention is to provide a machine of the above type wherein the sections referred to are yieldingly pressed toward each other so as to permit the same to yield to prevent the crushing of the jar neck where the glass runs very thin.

Another object of the invention is to provide a machine of the above type wherein the spinning rolls are so operated that one of the rolls is given a greater surface speed than the other, so as to feed the jar up to the spinning oll and to carry the same between the spinning rolls.

These and other ob ects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings which show by way of illustration one embodiment of the invention Figure 1 is a plan view of a machine embodying my improvements;

The invention is directed particularlyto a machine for turning the flange of a cap or band underneath the ledge on the neck of the jar. This is accomplishedv by two 0pposed spinning wheels rotating in the same direction and spaced a sufficient distance so as to engage the flange at substantially diametrically opposite points. These spinning wheels are provided with upper and lower sections, the edges of which are reversely inclined to the plane of rotation of the wheels so as to provide an inwardly tapermg groove adapted to receive the cap or band. The upper inclined face bears against the shoulder where the flange rests on the top of the jar neck, while the other inclined face engages the lower edge of the flange and bends or tucks the same underneath the ledge. The upper and lower sections of each spinning roll are mounted so that they may yield relativeto each other to prevent the breaking of the glass if it runs uneven. One of the spinning rolls is preferably of larger diameter than the other'so that they may be driven at the same speed and at the same time, the larger roll will have a greater surface travel. The jars are'fed by any suitable means at random to the spinning rolls. As the jar is brought into the space between the spinning rolls, itwill be engaged by the two spinning rolls. The smaller wheel rotates in a direction opposed to the travel of the jar'as it is brought to the spinning rolls, while the larger roll rotates'in the same di rection as the travel of the The result is that the larger roll which controls the position of the jar, draws it in between the two spinning rolls and causes the jar to pass between the rolls when the flange has been properlyfturned underneath the shoulder on the neck of the jar.

Referring more in detail to the drawings which show my preferred embodiment of the invention, the machine consists of a supporting frame 1' mounted on legs 2. 2. The frame 1 is in the form of a table extending from the receiving to the delivery end of the machine. Traveling over the table is an endless carrier 3. This carrier runs over a pulley 4 at the delivery end of the machine and the pulley 5 at the receiving end Fig. 1. The jars are placed thereon and of the machine. The pulley 4t is positively driven by means of a sprocket chain 6 which is operated by a sprocket wheel 7 on the main shaft 3. The main shaft 8 is driven by a belt wheel 9. Said main shaft is mounted in suitable bearings 10, 10 carried by the frame L The shaft 11 of the pulley 5 is mounted in a suitable bracket 12 so that it may be moved endwise by means of adjusting bolts 13 to put the endless carrier 3 under tension. The endless carrier 3 runs at a little distance abovethe table and I have provided rollersfl l and 15 to prevent saidendless carrier from sagging.

Extending upwardly-from the table is a standard 16 which carries an overhanging arm 17. Mounted in the overhanging arm 17 is a vertical shaft 13 carrying a spinning roll 19. This shaft 18 is mounted in a hearing 20 and is provided with a bevel gear 21 which mesh-es with the bevel gear 22 carried by the cross shaft 23 mounted in suitable bearings in this overhanging arm 17. On the outer end of the cross shaft 23 there is a sprocket wheel 24. A sprocket chain 25 runs over the sprocket wheel at and also over a sprocket wheel 26 on the main shaft 8. Thus it that the cross shaft 23 is rotated and this will impart rotation to the spinning roll 19. Also mounted on the overhanging arm 17 is a bearing 27 which is formed in two parts yieldin: y press-Bed toward each other by means of springs 23, 28 encircling bolts 29 passing through the lateral wings carried by the bearing sections. This forms a bearing,

the outer half portion of which is capable of lateral movement under the restraint of the springs 28. Mounted in this yieldingly constructed bearing is a shaft 30 which carrice the spinning roll 31. The shaft 30 also carries a bevel gear 32 meshing with a bevel gear 33 on the end of the cross shaft The spinning roll 19 is formed in two sections. The upper section is provided with a downwardly and inwardly inclined face 3 and the lower one is provided with an upwardly and inwardly inclined face 35. The upper sectionis rigid on its shaft. The lower section is pressed upwardly toward the upper section by means of a spring 36 which encircles the shaft and which bears at its lower end against nuts 37 threaded on to the end of the shaft. This provides a means whereby the lower section can yieldingly move away from the upper section. The spinning roll 31 is likewise formed in two sections with similarly inclined faces 38 and 39. The lower section is also yieldingly pressed upwardly by means of a spring 40 having a similar arrangement to the arrangement of the spring 36. The jar to be closed is indicated at J. The carrier moves in the direction of the arrow as shown in centeredon the carrier as near as possible. Suitable guides a1 and a9. mounted on standards 4:3 and 44, respectively, are arranged V so as to insure that the jar is in the center of 't-hecarrieras it approaches the spinning rolls. The spinning rolls are set atthe proper distance apart, so that the cap or band will pass into the groove formed be tween the inclined faces and the upper in clined faces of the spinningrolls' will engage the shoulder of the cap or band which rests on the neck of the jar while the lower inclined faces of the spinning rolls will engage the lower edge of the flange, the spin ning roll 19 is considerably larger in diameter than the spinning roll 31. The spinning rolls are rotated in the direction of the arrows, and it will be notedthat the smaller roll has a movement where it contacts with the cap or band in a direction 0pposed to the direction of travel of the carrier and the ar moves along therewith. The

other spinning roll has a movement at the point of contact with the cap or band in the same direction as the direction of the care ricr. The result is that as soon as the spinning rolls engage the jar, it will cause the jar to rotate about its axis, and this hr all parts of the flange or cap into enga ement with the spinning rolls so that the flange will be gradually bent or tucked underneath the ledge on the neck of the jar. l' -v hen the flange has been completely tucked underneath the ledge, then the jar will p between the spinning rolls andof course, will move between the spinning rolls in the same direction as the movement of the-can rier which brought the jar up to thespinning rolls. t only takes a short time to turn the edge of the flange on the cap or band underneath the ledge on the jar, and therefore, the will quickly pass between the spinning rolls and not interfere with the next approaching jar, so that the jars may be put promiscuously on the'carrier without requiring any special tin'iing thereof and they will be taken care of whenthey reach the spinning rolls. The are fed from the endless carrier on to a r tating disk '15. This disk is mounted on a shaft 46 which is rotated by a suitable connection with the shaft carrying the pulley t. A guide rail 47 directs the jars to one side and any suitable means can be provided, if desired, for taking the jars from this delivery disk.

In Figures land 5, I have shown a slightly modified form of feed in that T have provided means for insuring tiat the'jar will be broughtto a point where it will be,

gear li) at its lower end meshing with abevel 7 gear on the main shaft 8. This vertical shaft 48 carries tvo spaced feed wheels 51 and 52. These feed wheels are similarly shapot and are provided with segmental p ckets 53. These feed wheels, as above described, are positively rotated. 1 The a rs are fed into the segmental pockets, and as the feed wheel turns it will press the against the spinning rolls and hold the same in engagement with the spinning rolls until gripped and rotated thereby. The feed wheels will also insure that the next succeeding jar is held back until the jar in frontthereof has passed on through the spinning rolls.

It is thought that the operation of my device will be apparent from the above description. The operator places the jars with the caps or bands 10 sely applied thereto,

on the carrier slightly spaced from each other, but without any special care as to the exact spacing. The carrier moves the'jars forward until they are brought into engagement with the spinning rolls. The spinning rolls engaging the flange of the cap or band will cause the jar to be rotated and will lift the jar to a certain extent from the carrier so that it can be rotated. The jar is rotated for something more than one revolutionbefore the lower edge of the flange is tucked underneath the ledge on the neck of the jar suiflciently to permit the ar to pass between the spinning rolls. The yielding sections of the spinning rolls will give in order to prevent the breaking of the glassif there is unevenness in the vertical thickness of the shoulder on the neck of the jar. The bearii for the smaller spinning roll will yield so as to prevent the breaking of the glass if there is a slight unevenness or out-of-r0und ness in the neck of the jar.

it is obvious that minor changes in the details of construction and the arrangement the parts may be made without departing from the spirit of the invention as set forth in the appended claims.
